About these figures

This is a visualization of volcanoes in Indonesia. The map shows all volcanoes in Indonesia and the color scale indicates the size of the population living within 5km of the volcano. The more red the volcano, the larger the population living within 5km of the volcano and in a “danger zone”. The more green the volcano, the smaller the population is living within 5km and may be less of a danger. Zoom in and click on the volcano to see the volcano name, date of last eruption, elevation of the volcano and population size within 5km of the volcano.

The bar plot is visualization of the number of volcanoes per region in Indonesia and the types of volcanoes within each region. Hover over the plots to see the counts, region and volcano type.
